WAVE MOTOR.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed January 10,1907. Serial No. 351.590.

To all whom it may concern:

Be it known that I, JOHN CARSON, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Wave-Motors, ofwhich the following is a specification.

The object of the present invention is to provide an apparatus forutilizing the power of the waves of the ocean or other large body ofwater, which apparatus shall be efiicient in its action, durable in use,able to withstand severe storms, and capable of being quickly adjustedfor operation at various heights of the tides.

v In the accompanying drawing, Figure 1 is a sectional perspective viewof my apparatus; Fig. 2 is an enlarged plan view of the clamp; Fig. 3 isan enlarged plan view of a shoe; Fig. 4 is a side view of a modifiedform of the float.

.Referring to the drawing, 1 indicates piles, driven into the bed of theocean, or other body of water, and arranged in two parallel rows, therows being spaced a short distance apart, and the piles of each rowbeing also spaced a convenient distance to receive between them thefloats 2, which are preferably in the form of beams or logs.

Between the two rows of the piles l is a frame 3 consisting of the upperbeam 4 and the lower beam 5, connected at suitable intervals by thestanchions 6, (one such stanchion being here shown).

At a suitable distance from the rows of piles 1, depending upon thelength of the floats, and arranged parallel with said rows, are twoother rows of piles 7, and between the rows is a frame 8 consisting ofupper and lower beams 9, 1.0, connected, like the beams 4, 5, bystanchions 6, also a flooring 30 through which pass the piles 1, andside guide beams 31, which strengthen the frame and additionally guideit in its vertical movement.

The frame 3 serves as a support for the bearings 11 which are secured onthe lower beam 5, and on which the floats are individually pivoted, sothat the other ends of said floats can rise and fall freely with themotion of the waves, and the frame 8 serves to limit the motion of saidfree ends to prevent destruction or injury in case of severe storms.

The ends of the floats nearest their pivots are connected by links 12with levers 13, fulcrumed upon standards 14 on the upper beams 4, andconnected individually with air compressors 15, which serves to convertthe power furnished by the waves into a form suitable for transmission,and from which a pipe 16 conducts the compressed air to any desiredpoint where it can be utilized.

I provide convenient means for rapidly adjusting the apparatus for thevarying height of the tide. For this purpose the frames 3 and 8 aresecured to cables 17 passing around drums 18 on shafts 19 on theplatforms 20 secured on the tops of the piles. By turning the shafts 19,the frames 3 and 8 can be raised or lowered. Said frames are of suchspecific gravity that they float, or nearly so, when in their properposition in the water, and when they have taken this position they arequickly clamped by means of double cams 23 on shafts 24 extendingthrough the platforms and operated by handles 25, said cams bearingagainst shoes 26 which are thus pressed against opposite piles, saidshoes being slidably attached to the frames by means of bolts 27 in theupper beams passing through slots 28 in said shoes.

In the modification shown in Fig. 4, the floats are pivoted at theirextreme ends, and the links 12 are connected to the floats at pointsbetween said pivoted ends, and the free ends which rise and fall betweenthe piles 7.

By providing the several floats individually pivoted, so that they canrise and fall independently of each other, the force of the waves isvery effectively utilized. It will be seen, moreover, that the apparatusis very durable, and will withstand the action of severe storms. Alsothat it can be quickly adjusted to varying heights of the tides.Moreover the arrangement of the floats between the piles serves toconcentrate the force of the waves at points where they will produce themost effect in furnishing power.

I claim:

1. The combination of two parallel rows of piles, a pivot frame betweensaid rows consisting of upper and lower beams and suitable connections,two other rows of piles parallel with the first rows, a limiting framebetween the latter two rows, solid floats each passing at one endbetween adjacent piles of the first two rows, and at the other endthrough the limiting frame, and between piles of the rows adjacent tosaid latter frame, individual pivots for the floats on the pivot frame,means on said pivot frame for converting power, individual connectionsfrom said floats to said means, means supported at the top of thecorresponding rows of piles for raising each frame, and means operatablefrom said top for clamping each frame at any desired height relative tothe piles. substantially as described.

2. The combination of two parallel rows of piles, a pivot frame betweensaid rows consisting of upper and lower beams and suitable connections,two other rows of piles parallel with the first rows, a limiting framebetween the latter two rows, each frame being of a specific gravityapproximating that of water, solid floats each passing at one endbetween adjacent piles of one of the first rows, and at the other endthrough the limiting frame and between adjacent piles of the rowsadjacent to said latter frame, individual pivots for the floats on thepivot frame, means supported on said pivot frame for converting power,individual connections from said fioatsto said means, means supported atthe top of the corresponding rows of piles for raising each frame, andmeans operatable from said top for clamping each frame at any desiredheight relative to the piles, substantially as described.

3. The combination of two parallel rows of piles, a pivot frame betweensaid rows consisting of upper and lower beams and suitable connections,two other rows of piles parallel with the first rows, a limiting framebetween the latter two rows, solid floats each passing at one enrlpressed against opposite piles of the two rows, double between adjacentpiles of one of the first two rows, and at the other end through thelimiting frame, and between adjacent piles of the rows adjacent to saidlatter frame, individual pivots for the floats on the pivot frame, meanssupported on said pivot frame for converting power, indi vidualconnections from said floats to said means, means supported at the topof the corresponding rows of piles for raising each frame, and meansoperatable from said top for clamping each frame at any desired heightrelative to the piles, said means comprising shoes adapted to be camsadapted to engage said shoes for pressing" them against the piles, andshafts for said cams extending to the top of the piles, substantially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
